A federal agency says 380,000 pounds of possibly tainted deli meat products sold in sandwiches at Wal-Mart stores have been recalled by a food company in Buffalo.

The Department of Agriculture's Food Safety and Inspection Service says Tuesday that roast beef and ham distributed to Wal-Mart delicatessens might be contaminated with Listeria bacteria.

Agency spokesman Gary Mickelson says no illnesses have been linked to the meats made by Zemco Industries and most have already been consumed.

The sandwiches were removed from store shelves.

Mickelson says a retail sample collected in Georgia tested positive for Listeria monocytogenes.

The organism can cause serious and sometimes fatal infections in young children, frail or elderly people.
